Screenshots of the GPS chart for Garmin

Below is a raw sonar data dump, unedited, overlayed with The Corrib Chart. This is an area to the west of Cleenalaun where the lake bed is just a chaotic pile of rocks for a very large area. You can see that the Needles and Illaunagowna Shallows are simply the southern tip of this huge shallow formation, which varies between 8ft and 25 ft.
